1. Purpose
This policy explains how the NautilusTrader name, logos, and related branding (the “Trademarks”) may be used to avoid confusion while supporting legitimate open-source use.
2. Ownership
The Trademarks are owned by Nautech Systems Pty Ltd (“Nautech Systems”). Some Trademarks are registered in certain jurisdictions (including Australia) and others are protected under common law.
3. Relationship to Open-Source Software
This policy governs trademark and brand usage only and does not limit rights granted under the open-source license governing the NautilusTrader software.
4. Permitted Uses
Truthful, non-misleading nominative use is permitted, including referring to unmodified software and accurately describing forks (e.g., “derived from NautilusTrader”), provided no endorsement or official status is implied.
5. Prohibited Uses
You may not suggest sponsorship or endorsement, brand a fork as “official,” use Trademarks as primary branding for competing hosted services, or register confusingly similar domains or accounts.
6. Community Channels
Access to, promotion within, or use of official NautilusTrader community channels (including forums, chat servers, or mailing lists) for commercial products or services is permissioned and requires prior written approval from Nautech Systems. Participation in community channels does not imply endorsement or affiliation.
7. Use by Partners and Related Entities
Partners may use the Trademarks under the terms of a separate written partnership or co-branding agreement with Nautech Systems. Related entities may use the Trademarks only under a separate written license or authorization from Nautech Systems.
8. Enforcement
Nautech Systems may request modification or cessation of uses that violate this policy. Non-enforcement is not a waiver.
9. Changes
This policy may be updated from time to time. Updated versions will be published on the NautilusTrader website.
